HENRY W. S CHOFF, OF RIVER FOREST, ILLINOIS.

LIQUID-FUEL BiJRNER.

A To all whom it may concern: 7

Be it known that I, HENRY W. Sonorr, a vapor generating tube 6 as shown by the following is a specification.

citizen of the United States, residing at River Forest, in the county of Cook and State of Illinois, have invented a new and useful Liquid-Fuel Burner, of which the This invention relates to liquid fule burners and particularly to burners used in connection with sad irons. l

The primary object of this invention isto provide certain improvements over the burner shown in my former Patent No. 985,291 which issued February 28, 1911, to permit of the removal of the needle valve and the replacement thereof. I WVith the above and other objects in'view this invention is embodied in a novel construction, arrangement and combination of parts as hereinafter described and as shown in the accompanying drawings, in which similar reference characters indicate similar parts, and in which,

Figure 1 is a perspective view of the burner. Fig. 2 is a similar view of the burner, parts broken away and the removable section taken therefrom. Fig. 3 is a perspective view of the removable section. Fig. 1 is a perspective View of the fuel supply pipe. Fig. 5 is a sectional view in detail of the nipple for the connection of the supply pipe. Fig. 6 is a similar view. of the nipple and the fuel supply pipe attached thereto showing the various parts in section. Fig. 7 is a sectional view of the removable section, parts broken away, showing the means of coupling the vapor generating tube thereto.

Referring specifically to the drawings, 9 designates the hollow burner body and 6, the vapor generating tube which is looped around the sides and front end of the same. A lug 13 integral with the burner body 9 is arranged at one side and on top of the rear portion of the said body and has a rear lateral upstanding flange 11. A seat 22 is formed on the sideof the rear of the body and the inner faces of the flange 11 and the lug 13 are trimmed to form an abutment 32 adjoining the seat 22. This burner body is provided with a rib 16 on the side thereof adjacent the seat 22. Screw threaded sockets 23 and 241 are arranged in the seat 22 and in the side of the body 9 in front of the rib 16, respectively. The lug 13 carries the rear nipple 10 to which is arranged to be attached the supply pipe 37 and to the Specification of Letters Patent. Patented luay 28,1912, Application filed. July 21, 1911.

front of same is coupled one end ofthe coupling 14. A 'duct 33 leads from the nipple 10. through the lug 13 to the coupling 14: thus forming a passage for the liquid fuel from the supply pipe to the vapor generating tube.-

A removable section 18 having the rear upstanding lateral flange 12 is adapted to be set on the seat 22 and abut against the lug 13, the flanges 11 and 12 abutting against each other at their inner ends to form a continuous flange across the rear of the burner. The section 18 has the depending ear 20 on its outer end which fitssnugly in front of the rib 16 and over the screw threaded socket The section 18 and the ear 20 have the respective apertures 25 and 26 therein which. coincide or 'a'line with the sockets 23 and 241, and bolts 19 and 21, respectively, are passed through the apertures and engage in the sockets 23 and 2 1 to secure the section 18 in rigid position on the rear end of the burner body. The removable section 18 has an angle valve or vapor valve 36 of a suitable needle valve construction depending from the rear thereof having the orifice thereof disposed toward the burner body 9 to inject the vapor emitting therefroininto the burner body for combustion. The other end of the tube 6 is detachably coupled to the section 18 by the coupling 15 and the duct 31 forms a passage from the coupling 15 to the valve 36 whereby the vapor gener ated inthe tube ,6 passes through the duct 31 to the valve 36 to be injected into the burner body.

The coupling 15 is shownin detail in Fig. 7 and is effected in the manner directly described. A screw threaded recess or pocket 4:2 is provided in the inner face of the removable section 18 at the end of the duct 31 and a hollow screw threaded plug 28 having the hexagonal head 27 at one end and the section 29 secured thereto at the other end by a thin fragile web is first slipped over the end of the tube 6 and is screwed into the recess 32, the end of the tube also taking into the recess. The section 29 is adapted to seat on the shoulder at the rear of the recess and upon the plug being tightened the frictional contact of the section 29 with the shoulder causes it to break away from the plug and be compressed onto the end of the tube, thus forming a tight joint between the duct 31 and the tube 6. Upon removing the plug 28 the tube 6 and the section or collar 29 thereon can be readily removed from the recess to detach the tube from the removable section, and in an inverse manner can be attached thereto. The coupling 14 is simi lar to the coupling 15 and is therefore not thought necessary to be described in detail.

The nipple 10 is provided with a screw threaded stuffing box 34 near the end of the duct 33 and a pair of diametrically opposed notches 35 are arranged at the inner end of said stuffing box. The supply pipe 37 is provided with a screw threaded gland nut 39 having the hexagonal head 38 on the rear end and a washer 40 is arranged at the front end thereof. Diametrically opposed prongs 41 are formed on the end of the pipe 37 by crimping the pipe and project radially from the center of the said pipe. To couple the pipe 37 with the nipple 10 the end is passed into the stufling box 34 to engage the prongs 41 in the notches 35. The washer is then pushed inward and suitable packing (not shown), such as asbestos or the like, may be placed on same. The gland nut 39 is then screwed into the stuffing box to depress the packing to efl'ect a tight joint, the pipe 37 being held against rotatable movement by the prongs 41 which are engaged in the notches 35.

In using the burner the needle valve occasionally wears out before the burner body and by removing the bolts 19 and 21 and uncoupling the tube 6 from the removable section the said section can be removed from the burner body to carry with it the needle valve. Thus the worn out valve canbe replaced by securing a new section 18 to the burner body to renew the use of the burner. The tube section is tightly coupled to the new section by inserting the same with the collar 29 into the recess 42 and the plug 28 is screwed into the said recess to tightly clamp the collar 29 against the shoulder at the rear end of the said recess.

Copies of this patent may be obtained for five cents each, by Washington, I). 6.

Having described the invention what is claimed as new is 1. In a liquid fuel burner, the combination with a burner body having a lug on one end thereof, the said lug having a duct therethrough and means at the ends of the duct for the attachment of a supply pipe and a vapor generating tube, of a removable section, said section having a duct therethrough and means for the attachment of a vapor generating tube at one end of the last mentioned duct, a vapor valve for the burner body carried by the said section and in communication with the other end of the last mentioned duct, means for securing the said section to the burner body adjacent the said lug, and a vapor generating tube coupled to the said lug and to the said removable section.

2. In a liquid fuel burner, the combination with a burner body having a lug on one end thereof, the said lug having a duct therethrough and means at the ends of the duct for the attachment of a supply pipe and a vapor generating tube, of a removable section having an ear depending over the side of the burner body, the said section having a duct therethrough and means for the attachment of a vapor generating tube at one end of the last mentioned duct, a Vapor valve for the burner body carried by the said section and in communication with the other end of the last mentioned duct, the said section and ear being provided with apertures, bolts passed through the said apertures and engaged in the burner body, and a vapor generating tube coupled to the said lug and to the said removable section.

In testimony that I claim the foregoing as my own, I have hereto afiixed my signature in the presence of two witnesses.
